It seems that SourceLinks 2.1 slows down keyboard cursor in Visual Studio 2010 Professional / Windows 7 SP1 32-bit ( f.i., see http://stackoverflow.com/a/8168790/536172 ). Is this a known issue? Any plans to have it fixed? Any workarounds?
Are you seeing this in all files, or only in some files? Does this effect small / short files? Or only very large files? Which programming languages are you seeing this problem with?
I experience the slowdown of the keyboard cursor speed with large (50-60 KB) .CS files: when all their content is expanded in the editor (if most of the content is collapsed, no slowdown happens). .CPP files of similar size don't reveal the same issue.
